Description

Technical Field

[0001] The utility model relates to a sewing system, in particular to a double-layer sewing system for shirts. Background Art

[0002] The double-layer sewing process at the same position of the shirt sleeve is an important process to improve the quality of the shirt. This process significantly enhances the seam strength by performing two overlapping sewing at the same position. The existing double-layer sewing technology at the same position is widely used in high-end clothing manufacturing.

[0003] The existing process of double-layer sewing at the same position of shirt sleeves is: first, the sleeve fabric is positioned according to the requirements of the cutting piece, and then the first sewing is performed at the predetermined position; after completion, the second sewing is performed at the exact same position, so that the two seams overlap. This double-layer sewing structure has multiple advantages: it significantly improves the seam strength and extends the service life of the garment; it can effectively prevent the fabric from opening during repeated washing; at the same time, the overlapping seams can also form a unique three-dimensional visual effect, improving the product grade.

[0004] However, the existing double-layer sewing process at the same position has certain technical difficulties. The first is the difficulty of precise overlap: the second stitch must be precisely covered on the first stitch, and a slight deviation will affect the appearance. Due to the limitations of manual operation, it is difficult to ensure that the two stitches completely overlap, especially when dealing with longer stitches, it is difficult to maintain a consistent overlap.

[0005] In order to ensure that the two stitches overlap accurately, the operator needs to slow down and carefully control the position of each stitch. This cautious operation method greatly reduces production efficiency and increases the labor intensity of workers.

[0006] Therefore, it is of great significance to develop an automated system that can achieve precise overlapping sewing. Such a system needs to be able to accurately control the sewing position to ensure that the two seams overlap, while improving production efficiency and reducing operating difficulty, thereby improving product quality and production efficiency.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, a double-layer shirt sewing system includes a main circuit and a control circuit.

[0024] The main circuit includes a motor M1 and a motor M2. The motor M1 is used to sew the shirt sleeves, and the motor M2 is used to transport the shirt sleeves to move the roller system.

[0025] The motor M1 is connected to a thermal relay FR1. The thermal relay FR1 is connected to a relay KM1. The relay KM1 is used to control the motor M1 to rotate forward and the sewing machine to sew.

[0026] The motor M2 is connected to a thermal relay FR2. The thermal relay FR2 is connected to relays KM2 and KM3. Relays KM2 and KM3 are connected in parallel. Relay KM2 is used to control the forward rotation of the motor M2, and relay KM3 is used to control the reverse rotation of the motor M2.

[0027] The control circuit includes a forward rotation circuit 8 for causing the motor M1 and the motor M2 to rotate forwardly, and a reverse rotation circuit 9 for causing the motor M1 to rotate forwardly and the motor M2 to rotate reversely.

[0028] The forward circuit 8 includes a first branch 1. The first branch 1 includes a push switch SB2 and a normally open switch KA1. The push switch SB2 is connected in parallel with one of the normally open switches KA1. The push switch SB2 and the switch KA1 are commonly connected with a normally closed switch KT1 and a normally closed switch KT2. The normally closed switch KT2 is connected with a relay KA1. When the operator operates the push switch SB2, the circuit is turned on, and then the relay KA1 works, and the normally open switch KA1 is closed, so that the normally open switch KA1, the normally closed switch KT1, the normally closed switch KT2 and the relay KA1 form a stable path.

[0029] The forward circuit 8 also includes a second branch 2. The second branch 2 includes a normally open switch KA1. The normally open switch KA1 is connected to a normally closed switch KT1, and the normally closed switch KT1 is connected to a thermal contactor FR1. The thermal contactor FR1 is used to control the action of the thermal relay FR1 in the main circuit and disconnect the circuit when overloaded. The thermal contactor FR1 is connected to a contactor KM1. When the relay KA1 is turned on, the normally open switch KA1 is closed, so that the second branch 2 is turned on, the contactor KM1 works, so that the relay KM1 in the main circuit is closed and turned on, and the motor M1 rotates forward.

[0030] The forward circuit 8 also includes a third branch 3. The third branch 3 includes a normally open switch KA1. The normally open switch KA1 is connected to a normally closed switch KT2, and the normally closed switch KT2 is connected to a thermal contactor FR2. The thermal contactor FR2 is used to control the action of the thermal relay FR2 in the main circuit and disconnect the circuit when overloaded. The thermal contactor FR2 is connected to the contactor KM2. When the relay KA1 is turned on, the normally open switch KA1 is closed, so that the third branch 3 is turned on, the contactor KM2 works, so that the relay KM2 in the main circuit is closed and turned on, and the motor M2 rotates forward.

[0031] The forward circuit 8 also includes a fourth branch 4. The fourth branch 4 includes a normally open switch KA1. The normally open switch KA1 is connected to a normally closed switch KT1, and the normally closed switch KT1 is connected to a power-on delay relay KT1. When the power-on delay relay KT1 is turned on, timing starts, and is used to control the state switching of the normally closed switch KT1. When the relay KA1 is turned on, the normally open switch KA1 is closed, so that the fourth branch 4 is turned on, the power-on delay relay KT1 works, and timing starts. At the end of the timing, the state of each normally closed switch KT1 is switched to off.

[0032] The forward circuit 8 also includes a fifth branch 5. The fifth branch 5 includes a normally open switch KA1. The normally open switch KA1 is connected to a normally closed switch KT2, and the normally closed switch KT2 is connected to a power-on delay relay KT2. When the power-on delay relay KT2 is turned on, timing starts, and is used to control the state switching of the normally closed switch KT2. When the relay KA1 is turned on, the normally open switch KA1 is closed, so that the fifth branch 5 is turned on, the power-on delay relay KT2 works, and timing starts. At the end of the timing, the state of each normally closed switch KT2 is switched to open.

[0033] Under the above-mentioned forward rotation circuit 8 setting, when the relay KA1 is working, the motors M1 and M2 rotate forward, and when the timing of the power-on delay relays KT1 and KT2 ends, the normally closed switches KT1 and KT2 are disconnected, so that the relay KA1, the contactor KM1, the contactor KM2, the power-on delay relay KT1, and the power-on delay relay KT2 are all in an open circuit state. The motors M1 and M2 stop. At this time, the sewing system reaches the sewing end position of the sleeve and completes the first sewing process.

[0034] The reversing circuit 9 includes a sixth branch 6. The sixth branch 6 includes a normally closed switch KA1, and the normally closed switch KA1 is connected to a normally closed switch KT3. The normally closed switch KT3 is connected to a power-on delay relay KT3. The power-on delay relay KT3 is connected to a thermal contactor FR2. The thermal contactor FR2 is connected to a contactor KM3. As mentioned above, when the relay KA1 is turned on, the normally closed switch KA1 is turned off. After the first sewing process is completed, the relay KA1 is turned off and loses power, so that the normally closed switch KA1 is reset and turned on, thereby turning on the entire sixth branch 6. The power-on delay relay KT3 starts timing, and the contactor KM3 works, so that the relay KM3 is closed, the motor M2 reverses, and the shirt sleeve starts to move in the opposite direction. At the end of the timing, the normally closed switch KT3 is turned off, the contactor KM3 is disconnected, and the motor M2 stops.

[0035] The reversing circuit 9 includes the seventh branch 7. The seventh branch 7 includes a normally closed switch KA1, and the normally closed switch KA1 is connected to a normally closed switch KT4. The normally closed switch KT4 is connected to a power-on delay relay KT4. The power-on delay relay KT4 is connected to a thermal contactor FR1. The thermal contactor FR1 is connected to a contactor KM1. As mentioned above, when the relay KA1 is turned on, the normally closed switch KA1 is turned off. After the first sewing process is completed, the relay KA1 is turned off and loses power, so that the normally closed switch KA1 is reset and turned on, thereby turning on the entire seventh branch 7. The power-on delay relay KT4 starts timing, and the contactor KM1 works, so that the relay KM1 is closed, and the motor M1 rotates forward. At the end of the timing, the normally closed switch KT4 is turned off, the contactor KM1 is disconnected, and the motor M1 stops.

[0036] Under the setting of the above-mentioned reversing circuit 9, the second motor reversing sewing is realized.

[0037] In summary, the sewing system described in the present application can achieve the first sewing of the sleeve during the transportation process through the forward rotation of the motor M1 and the forward and reverse rotation of the motor M2, and then perform the second sewing when the sleeve is transported back to its original position, thereby achieving a double-layer sewing effect.

[0038] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
